Sen. John McCain appeared poised to be the savior of the GOP health bill when he returned to the Capitol earlier this week despite brain cancer.

He turned out to be the bill's executioner.

In an astonishing development early Friday, the longtime Arizona senator turned on his party and his president, joining two other GOP senators in voting "no" on Republicans' final effort to repeal "Obamacare."

The chairman of the House Intelligence Committee is accusing top political aides of President Obama of making hundreds of requests during the 2016 presidential race to unmask the names of Americans in intelligence reports, including Trump transition officials.

Intelligence Chairman Devin Nunes (R-Calif.), in a letter to Director of National Intelligence Dan Coats, said the requests were made without specific justifications on why the information was needed.

The top Democrat on the House Natural Resources Committee is calling for a probe into whether President Trump’s Interior secretary threatened to retaliate against an Alaska senator for opposing the GOP healthcare measure this week.

Both Alaska Sens. Lisa Murkowski (R) and Dan Sullivan (R) said they received a call from Interior Secretary Ryan Zinke on Wednesday, informing them that the Trump administration will not support key projects in Alaska after Murkowksi voted against the GOP healthcare bill in the Senate a day before.

The Senate Judiciary Committee has dropped a subpoena against Paul Manafort and plans are underway for the former Trump campaign chairman to speak to investigators, a source familiar with the situation said on Tuesday.

Manafort separately provided information to the Senate Intelligence Committee Tuesday on a June 2016 meeting he participated in with a Kremlin-connected lawyer who had promised damaging information on Hillary Clinton.

Senate Republicans voted to advance to floor debate on their efforts to repeal and replace Obamacare. Vice President Mike Pence cast the tiebreaking vote.

In a dramatic moment, Sen. John McCain returned from Arizona to applause from fellow senators. He case a necessary Republican vote for the motion after two GOP senators sided with all Democrats in opposition.

As the vote began, protesters in the Senate gallery shouted "kill the bill" and "shame, shame, shame!"

Jared Kushner, President Donald Trump's son-in-law and senior advisor, plans to testify to the Senate intelligence committee on Monday morning that he "did not collude" with Russia or any other foreign government.

"I did not collude, nor know of anyone else in the campaign who colluded, with any foreign government," Kushner states in prepared testimony submitted to the committee and made public ahead of the meeting Monday. "I had no improper contacts. I have not relied on Russian funds to finance my business activities in the private sector."

TVNL Comment: Watch for updates as the Kushner testimony continues.

Update: 11:00 am: President Trump’s son-in-law and adviser, Jared Kushner, released new details Monday about his contacts with Russian officials, including a previously undisclosed encounter with Ambassador Sergei Kislyak in April 2016.
